The specific embodiment
In Figure 1A-1E, illustrate according to milling cutter 10 of the present invention, it is used to the important molding tool of molding industrial processes.This milling cutter has knife rest, and described knife rest has the anti-dandruff end 12 of axle 11 and front.End 12 has two cutting tip bases 13,14, and each is all for carrying the cutting tip 30 of preferably being made by sintered hard alloy according to of the present invention.Clamping device or screw 15 are fixed on cutting tip in the cutting tip base.This cutting tip 30A, 30B so arrange so that one of them cutting tip or the inside cutting tip 30A that is arranged in inner cutting tip base 13 extend to and the preferred centre line C L by cutter.This means that this cutter can hole in workpiece.The second cutting tip or the outside cutting tip 30B that is arranged in outside cutting tip base 14 are arranged on centre line C L one side slightly.Effective cutting edge of cutting tip is arranged so that they form complete hemispherical when rotated.
Each cutting tip base 13,14 includes basal surface 16, and it has to receive the screwed hole of centre 21 of screw 15.And this cutting tip base has front shoulder 17 and rear shoulder 18, and their position is relevant with the axial direction of cutter.This basal surface 16 comprises two projections 19,20, and they are arranged on the both sides in hole 21 and different apart from the distance in this hole.Be positioned at vertically the radially outer enveloping surface that is connected to cutter of anterior projection 19 and radially innerly extend to only about half of distance towards front shoulder 17.Be positioned at vertically the radially inner location that is connected to rear shoulder 18 of the projection 20 at rear portion and radially outerly extend to only about half of distance along the direction towards enveloping surface.In inner cutting tip base 13, each projection 19,20 bearing of trend all form sharp angle α with centre line C L, see Fig. 1 F.Externally in the cutting tip base 14, each projection 19,20 bearing of trend all form acute angles beta with centre line C L, see Fig. 1 G.Angle [alpha] is less than angle beta.Each projection 19,20 all has and substantially be that the cross section of rectangle, this cross section have the slightly top side of inclination.
As mentioned above, be suitable for being arranged in two blade bases 13,14 at the cutting tip 30 shown in Fig. 2 A-2F.This cutting tip is asymmetric about the straight line in the hole 31 by cutting tip.The hole 31 of described straight line and cutting tip and two cutting corner 36,37 all intersect.This cutting tip has so-called eye shape or Leaves'Shape and comprises two cutting edge parts in plan view, each cutting edge part by along the intersecting lens separately between clearance plane 34A and chip surface 35 substantially be straight cutting edge 32,33 and in plan view crooked cutting edge 38,39 formations.Crooked cutting edge 38,39 has different length.Straight cutting edge 32,33 and not parallel but each other shape have a certain degree, this angle is favourable is between 4 and 20 degree, preferably between 6 and 15 degree.This straight cutting edge is along being connected to crooked cutting edge 38,39 towards relative cutting corner 36,37 direction.Crooked cutting edge 38,39 by for example 5 and 25mm between radius limit.Crooked cutting edge 38 is consistent with the circular arc of about 85 to 97 degree, and crooked cutting edge 39 is then consistent with the circular arc of about 95 to 107 degree. Curved edges 38,39 has the basic radius that equates under installment state.Crooked cutting edge consists of 40% of cutting tip development length at least.Crooked cutting edge 38,39 is convex in the side view according to Fig. 2 C.The bottom 34B of clearance plane 34 and the bottom side of cutting tip 40 form the obtuse angle.The top 34A of clearance plane 34 is basically perpendicular to the bottom side 40 of cutting tip.This top 34A guarantees to be attached thereto the cutting edge that connects can obtain higher intensity.
Be provided with two grooves or groove 41,42 on the bottom side 40.Each groove 41,42 only intersects with a clearance plane 34 below curved cutting edge 38,39.Therefore, described groove only has limited development length on the longitudinally direction transverse to cutting tip, and is subject to the restriction of end wall 43.The described development length of groove is greater than 50% of the width that reeded basal surface 40 wherein is set.A zone of corresponding bottom side 40 is not subjected to the impact of groove, and therefore can keep feasible stayed surface for cutting tip.Described groove has the cross sectional shape of truncated triangles.Groove 41 is compared the more close hole 31 of setting with groove 42, and therefore this cutting tip only can be positioned in the cutting tip base in one way.
It is usefulness and constant in axial machining that curved cutting edge makes it possible to provide along whole edge.
Cutting corner can be divided into sharp corner 36 and obtuse corner 37.This obtuse corner has dual-use function; be positioned at the cutting tip at center with protection when the processing sturdy material is for example holed; and when cutting tip has been arranged in the outside cutting tip base, thereby will producing full curve, this bight 37 makes it possible to dark shoulder is carried out various processing.Sharp corner 36 is only externally useful in the cutting tip base 14.This obtuse corner 37 is limited by radius R 1 in according to the plan view of Fig. 2 A, and it is at least the twice of the radius R 2 that limits sharp corner 36.This obtuse corner 37 has negative anti-dandruff angle and from chip surface 35 along 40 direction tilts towards the bottom side.Sharp corner 36 has positive anti-dandruff angle and consists of the continuous extension of chip surface 35.This cutting tip has around the hole central part 44 of 31 rising.This central part 44 can be used as chip-breaking.Central part 44 includes sign, and one of them bead (knob) expression periphery is installed and two beads represent the center installation.In blade base 13 and 14, also has corresponding sign.
The optional embodiment that Fig. 3 A-3F illustrates according to cutting tip of the present invention is cutting tip 30 '.This cutting tip 30 ' is with the difference of aforesaid cutting tip 30, and this cutting tip 30 ' is formed with optimization and is used for difficult processing with the chip-breaking of the workpiece material of turning.Identical reference marker provides identical details.Described chip-breaking is made of the recess 51,52,53 and 54 that lays respectively in the cutting edge 32,33,38 and 39.Each recess all extends downward among the top 34A of clearance plane and extend certain distance in chip surface 35.Such as what can observe from the plan view according to Fig. 3 A, recess 51,54 and 52,53 is set to respectively substantially flush with groove 41 and 42.
40 periphery can have the inclined-plane and has larger radius so that the cutting tip base can form cutting tip 30,30 ' along the bottom side.
Cutting tip 30,30 ' is installed in the following manner.Thereby cutting tip 30A is relied on outside cutting tip base 13 so that groove 41,42 and protruding 19,20 aligns.In proper position, can be with in screw 15 patchholes 31 and in hole 21, tighten.Thus, the bottom side 40 of cutting tip is pressed against on the basal surface 16, and simultaneously three parts of the space of clearance plane 34B will be resisted against on the shoulder 17,18 in the cutting tip base 13.Only processing so that be allowed to produce when moving a little at this situation cutting tip, the side of projection is just against groove 41,42.When cutting tip 30B being installed in the inner cutting tip base 14, the bottom side 40 of cutting tip is pressed against on the basal surface 16, and simultaneously two parts of the space of clearance plane 34B will be resisted against on the shoulder 17,18 in the cutting tip base 14.With the same in the cutting tip base externally, projection only just cooperatively interacts under the load of cutting tip 30B with groove.Because groove 41 only intersects at a side and clearance plane, being positioned at vertically anterior projection 19 will be against end wall 43 when screw may deflection occur, and can prevent further that thus cutting tip from getting loose.
Therefore, the present invention relates to a kind of milling cutter and cutting tip, it is so that cutting tip can position accurately, and wherein cutting tip can firmly be clamped.To this cutting tip to support with the mode of optimizing accurately.This cutting tip can not produce unexpected motion.
